Ping not working on your network?

In real environments, ICMP is often blocked — but that doesn’t mean hosts are invisible.

In this video, I show how cybersecurity professionals still discover active systems using ARP-based techniques with NetDiscover, even when ping fails completely.

This is a high-level walkthrough focused on:
• Why ping is blocked in real networks
• How ARP discovery works differently than ICMP
• How SOC analysts and defenders identify hosts anyway
• When tools like NetDiscover are useful (and when they’re not)

No memorized commands. No hype.
Just how host discovery actually works in real networks.

This is ideal for:
• Security+ and Network+ students
• Aspiring SOC analysts
• Anyone confused when ping suddenly “stops working”
